Structured PICO

Population

HeLa cell extracts and recombinant U2 small nuclear ribonucleoprotein particle (snRNP) A' protein

Intervention

Mutational analysis of the central core region of A' protein

Outcome

Reconstitution into U2 snRNPs and direct binding to U2 RNA

The Leu-Leu motif of the A' protein is essential for its reconstitution with U2 snRNPs through protein-protein interactions.
